Why can't I print any maps in Yahoo! Maps? A fist pops up . . .?

I can't print any maps. I click on Printable Version, a fist pops up and closes, then a tiny window pops up with a Print on. I click on the Print on, nothing happens, and the window disappears in about 3 seconds. There isn't enough time to copy, as the window is very small and disappears almost immediately.
